Crossrail cross section

This boring Crossrail pamphlet is nevertheless worth looking at for the cross section of the central tunnel, showing how it weaves past the other tube lines.

It's not necessarily a pro-Crossrail diagram though, as it very clearly shows how trains will sail past the Piccadilly Line at Holborn with no connection, and how the east end of Bond Street station will be very close to the Victoria and Bakerloo Lines, again with no connection as Oxford Circus is already overcrowded.
